Title: Apparatus for detecting flow rate of sucked air
Inventor: SAKURAI OSAMU
IPC: F02D45/00
Filed: 1988-11-24
Abstract: PURPOSE:To enhance detection accuracy by calculating the average values of two detection signals by discriminating the signal of a part where the effect of a back flow does not reach on the basis of the difference between two detection signals corresponding to the predetermined cycle of a sampling cycle. CONSTITUTION:When an engine is within a low rotation high load region, an air sucking cycle T(=30/N wherein N is the number of rotations of the engine) is divided into (n)(= an even number between 10-100) equal sampling cycles DELTAt and a sucked air flow rate at every sampling cycle DELTAt is read as a detection signal Qa on the basis of the flow velocity detected by a hot wire element and the detection signals q1, q2 corresponding to the predetermined cycle of the detection signal Qa, for example, the half cycle T/2 of the cycle T. The signal difference di=q1-q2 between both signals q1, q2 is operated and, in the case of the absolute value of the signal difference di < predetermined value ds, the sucked air flow rate is operated and detected as Q=(q1+q2)/2. In the case of difference di > value ds, the signal difference di-1 of the signal previous by the cycle DELTAt is operated. When the codes of the differences di, di-1 are different, the sucked air flow rate Q can be detected from the average value of the detection signals q1, q2.

Title: C-axis datum correction device for spindle
Inventor: EZAKI TAKESHI
IPC: G05D3/12
Filed: 1990-10-31
Abstract: PURPOSE:To automatically determine the processing datum of a work after the work has been set on a work table arbitrarily by detecting the position of a reference recessed section based on signals from a pressure difference detector, which are generated when an air nozzle is faced to the reference recessed section of the work, and thereby making the position the processing datum. CONSTITUTION:An air nozzle 7 is pressed on the end face of a work W with a bite holder 3 controlled in the Z axis against the work W which is provided with a reference groove or a reference hole Wa in its end face. In the second place, compressed air is fed with an electromagnetic changeover valve 14 turned on, compressed air regulated by a regulator 15 is regulated by an air resistance difference pressure switch 16 so as to be fed out of a line 17 to the rotary joint 12 of the bite holder 3 via the air resistance difference pressure switch 16, so that it is thereby jetted out of the air nozzle 7. Following which, the specified amount of function is generated, the inching of a spindle drive motor is operated. And if the difference in pressure becomes zero when the reference groove or the reference hole Wa comes in front of the air nozzle 7, an 'ON' signal is outputted from the air resistance difference pressure switch 16, the rotation of a spindle is then suspended, and the position is thereby made to be the processing datum of the work.

Filed: 1989-11-15
Abstract: PURPOSE:To reduce the labor of an operator by determining the number of mounting parts between a parts feeding equipment of a mounting head and a printed board, on the basis of the comparison results of each position data stored in a check memory. CONSTITUTION:In an N CHECK1 memory 96, an N CKECK2 memory 97 and an N CHECK3 memory 98 of a RAM 92, nozzle fixing number data for each step of NC data are stored, in order to determine individual data of step number to be stored in a step length counter 95. A CPU 90 compares whether the contents of each of the data stored in storage devices 96-98 are mutually different. On the basis of the comparison results, the CPU 90 determines the number of mounting parts for one reciprocation between a parts feeding equipment of a mounting head and a printed board. Thereby it is unnecessitated to make up data as to how many nozzle are to be used during the above one reciprocation, and automatic determination is provided, so that the labor of an operator can be omitted.

Title: Motor stopping device
Inventor: TSUBOUCHI TOSHIKI
IPC: H02P3/10
Filed: 1992-11-06
Abstract: PURPOSE:To provide a simple device for stopping motors used in a variety of electric devices which swiftly brings a motor into a complete stop. CONSTITUTION:The device consists of a motor driving means 2 for a motor 1, torque direction switching circuit 3, integrating circuit 4, judging circuit 5, mono-multi circuit 6, and speed detecting circuit 7. When a motor stop command is delivered, the torque direction switching circuit 3 changes the direction of the torque applied to the motor 1 from forward to reverse. While the motor speed is high, a large reverse torque is applied, rapidly decelerating the motor. When the speed is reduced, the reverse torque is decreased to relieve the deceleration of the motor. The instant the motor rotation, after its speed being reduced to zero, is reversed, it is detected by a reversing detection circuit 8, and the mono-multi circuit 6 is controlled to stop the application of reverse torque to the motor. This prevents the reversing of motor revolution, swiftly stopping the motor.

Title: Thin film laminated body and formation thereof
Inventor: KANEKO YOSHIMI
IPC: H01L21/30
Filed: 1991-11-13
Abstract: PURPOSE:To form the thin film layers of a thin film laminated body by successively forming a first and second thin film layers on a substrate so that cracking of the shoulder sections of the thin film layers can be prevented and the layers can be stabilized by forming the second layer to have a trapezoidal longitudinal section with sloped side faces. CONSTITUTION:After applying a resist 17 to the surface of a lead film 12 (second layer), the resist 17 is formed only in an area proposed to the formation of an MT element film 10 (first layer) or the lead film 12 by performing alignment and development on the resist 17. Then the films 12 and 10 are successively etched. After etching, the film 12 is again etched. When the film 12 is again etched, the part of the film 12 below the resist 17 is over-etched, because the part of the film 12 to be etched has been etched by the previous etching. In other words, the film 12 is etched even to the section below the resist 17. Therefore, the side faces of the film 12 below the resist 17 become slopes, because the side faces are also etched to some extent.
